A position sensing system for a braking system has a rotor and a caliper assembly disposed at least partially around the rotor. The caliper assembly has a fixed mount bracket and a floating portion. At least two brake pads are attached to the floating portion, operable to exert a force against the rotor in response to a force through the floating portion. A first portion is coupled to the fixed mount bracket. A second portion is coupled to the floating portion such that the second portion moves in response to movement of the floating portion. A sensor assembly measures a distance between the first portion and the second portion. A wireless transmitter sends a signal from the sensor assembly to detached electronics, the signal representing the distance measured.
